6 Claims. (Cl. 220-113) This invention relates to multi-celled article carriers designed to permit fiat collapse thereof when shipped and stored but readily expansible into erected form to receive articles in the cells thereof.

Twin compartrnented article carriers having any desired even number of cells are constructed in accordance with this invention from two blanks of paperboard or fiberboard material which are substantially rectangular in form. One of the blank parts provides the center partition structure having handle forming portions which are reinforced and strengthened by handle facing flaps which together provide a handle part of at least four ply thickness. This blank also provides the end panel sections and both pairs of end cells for the carrier. The companion blank part provides the collapsible bottom panel and the paired side panels which are adhesively attached to the side wall liner sections forming a part of the end cells associated with the first blank part. Where the carrier is to be equipped with more than six cells, the intermediate cells are formed from top and bottom wings integrally associated with either the first blank part or the second blank part.

The blank part which forms the center partition and end cell structure of the carrier presents a pair of center partition panels which are foldably connected along the top edge thereof, with an end cell forming wing foldably connected to each end edge of both center partition panels. The handle facing flaps are captured from material between adjacent end wings of the blank and are foldably connected to the adjacent end edges of the center partition panels in a manner to permit high speed folding thereof into adhesive contact with the upper handle forming portions of the center partition panels. The cell forming end wings of the blank are designed to be speedily assembled into collapsed tubular form and into overlying relation to the respective center partition panels with which they are associated. The side panels of the companion blank are then adhesively secured to the side wall'liner sections of the collapsed cells of the first blank to complete the carrier in collapsed form.

The intermediate cells are formed from top and bottom wings foldably connected to the bottom edges of the center partition panels of the first blank. The intermediate cell forming wings of the blank are assembled into collapsed tubular form before the paired blanks are joined together.

Carriers made in accordance with this invention are strong and sturdy in construction and present full height cross partitions which extend down to the erected bottom panel of the carrier. By making the carrier of two separate blanks, the bottom and side panel forming blank may be made of heavier or stronger paperboard or fiberboard material than the blank which forms the center partition and end cell structure of the carrier. As a result of this permissible selection of two different stock sheet materials, carriers can be made in accordance with this invention which have bottom panels which will carry States atent O 2 substantially heavier article loads than otherwise attainable.

Other objects and advantages of this invention will become apparent as the disclosure proceeds.

Although the characteristic features of this invention will be particularly pointed out in the claims, the invention itself, and the manner in which it may be carried out, may be better understood by referring to the following description taken in connection with the accompanying drawings forming a part hereof, in which Fig; 1 is a plan view of a blank designed to form both the end and intermediate cells and the center partition structure for a twelve bottle carrier; areas of adhesive being shown applied to certain parts of the blank in preparation for the first folding operation;

Similar reference characters refer to similar parts throughout the several views of the drawings and the specification.

The two blank parts. from which these carriers are formed are cut from stock sheets of selected paperboard or fiberboard material which need be imprinted on one side thereof only. The two blanks maybe cut and scored from the same or different stock sheets on an' automatic cutting and scoring machine at high production speeds with very little or no waste material resulting. The two blanks are adapted for high speed assembly into carrier form on automatic gluing and folding machines having means operative to register a side wall panel of one. blank part with one set of collapsed cells associated with the other blank part.

Figs. 1 and 2 show a pair. of prepared blanks A" and B from which a twelve cell carrier may be made and assembled in accordance with this invention. as. shown in Figs. 11, 12 and 13. The blank, A! provides: the center partition structure and all the cells for this twelve cell carrier while the blank B provides the bottom and. side panels thereof. The blankA." comprises a pair of center partition panels 1-1' foldably connected. along a top edge forming score. 11, the center partition panels 1-1' being sized to extend the full length of the twelve cell carrier and down to the erected bottom panel thereof. Av pair of left hand wings w1- and w-3 is foldably connected along alignedv scores 13-I3 to the. adjacent end edge of the center partition panels 1-1, a pair of right hand wings w2 and w-4 is. foldably connected along aligned scores 12-12 to the opposite end edges of the center partition panels, and a pair of top and bottom wings w-S and w-6 is foldably connected to the bottom ends of the center partition panels 1-1. along parallel extending hinging scores 50-50.

The left hand wings w-l and w3 form one pair of end cells for the carrier and comprise a pair of end panel sections 3-3 foldably connected along the aligned scores 13-13 to the adjacent end edges of the center partition panels 1-1, a pair of side wall liner sections -5 foldably connected along the aligned scores -15 to the end panel sections 3-3, a pair of cross partition sections 7-7 foldably connected along aligned scores 17-17 to the side wall liner sections 5-5 and a pair of center partition securing flaps 9-9 foldably connected along aligned scores 19-19 to the cross partition sections 7-7'. The right hand wings w-2 and w-4 form the other pair of end cells for the carrier and likewise cont prise a pair of end panel. sections 2-2. foldably connected along. aligned scores 12-12 to the opposite end edges of the center partition. panels 1-1, a pair of side wallliner sections 4-4 foldably connected along. aligned scores 14-14 to the end panel sections 2'-2, a pair of cross partition sections 6-6 foldably connected along aligned scores 16-16 to the cross partition sections 6-6, and a pair of center partition securing flaps 8-8 foldabl-y connected along aligned scores 18-18 to the cross partition sections 6-6.

One pair of handle facing flaps 10-10 is captured from. otherwise wasted material between the left hand wings w l and w-3 and are foldably connected at one end. thereof to the adjacent end edge of the cente'rpartfl tion panels 1-1 along aligned scores 13 which are sub stantially in alignment with the scores 1313-. A second pair of handle facing flaps 10-10 may also-be captured from material between the right hand wings w-Z and WA and are foldably connected at one end thereof to the opposite end edges of. the center partition panels 1-1' along aligned scores 12" which are substantially in alignment with the scores 12-12. Each pair of handle facing flaps 10-10 is separate from each other by acut 11 extending. substantially in alignment with the top edgeforming score 11 and are-separated by cuts'20-20 from the upper edges of the adjacent wings. The center I partition panels 1-1 are also provided with hand hole cutouts 21 with which hand holev cutouts 21- formedinboth pairs of the handle facing flaps 10-10 align when the handle facing flaps 10-10 are folded over the upper handle forming portions of the center partition panels 1-1 as shown in Fig. 3. The handle part for the carrier is thus of four ply thickness at the end portions thereof, and of six ply thickness in the area of the hand hole cutout 21 where the free ends of the handle facing flaps 10-10 overlap as shown in Fig. 13.

The upper and lower wings w-5 and w-6 which. form the intermediate cells of the carrier comprise a pair: of center partition liner sections 51-51 foldably connected by scores -50 to the adjacent lower edges of the center partition panels 1-1. As shown in Fig. l, a pair of intermediate cross partitions 53-53 is foldably connected along aligned scores 63-63 to the left end edges of the center partition liner sections 51-51, a pair of side wall liner sections -55 is foldably connected along aligned scores -65" to the adjacent intermediate cross partition. sections 53-53, a further pair of intermediate cross partitions 57-57 is foldabl y connected along aligned scores 67-67 tothe adjacent side-wall liner sections 55-55, and a pair of center partition liner flaps. 59-59 is foldably connected along aligned scores 57-57 to the adjacent cross partition sections 57-57. An additional pair of cross partition sections 52-S2' is foldably connected along. aligned scores 62-62 to the right end. edges of the adjacent center partition liner section'5 by aseparating cut 61.. The connected sections 52 and 54 are likewise separated from the bottom edge of the center partition panel 1 and the adjacent end panel section 2 by a separating cut 60 substantially in-alignment with the: separating cut 61. The foldably connected sections 53, 55 and 57 and the associated center partition liner flap 59 are likewise separated from the bottom edge of the. center partition: panel 1, the adjacent end panel section 3 and the adjacentside wall liner section'- 5" by azseparatin'gcut' 61" as shown in Fig. 1. Similarly, the foldably connected sections 52 and 54- are separated from the bottom edge of the center partitionpanel 1" andthe adjacent end panel section 2 by" a separating cut 60 extending substantially in: alignment withthe cut 61. The bottom. and side panel forming blank B as shown in: Fig. 2 comprises a pair-of bottom panel sectionsv; The bottom and side panel forming blank B may be formed. from thesame' stock sheet materialas its. com.

panion center partition and cell forming-blank. A.;;or-

desired, the blank B may be formed from heavier or stronger stock sheet material.

The center partition. and cell forming blank A. as shown in Fig. 1 is assembled by applying adhesive areas n-a.

over the entire faces of both pairs of handle. facing flapspaired handle facing flaps 10-10 at the. left hand. side of! the blank may then be folded along'the. alignedscores v greases 13 so as to become adhesively secured to the upper handle forming portions of the center partition panels 1-1, with the free ends of both pairs of facing flaps adhesively secured together in partially overlapped relationship as shown in Fig. 3. To facilitate this folding operation, both pairs of handle facing flaps -10 may be temporarily connected by interrupting the cut lines 11 to leave a breakable connecting neck 11" which holds the panel facing flaps together so that they can be folded as paired units.

In the same gluing operation, adhesive strips b-b are applied to the center partition liner flaps 9-9 and the left hand wings w1 and w-3 then folded along the aligned scorces -15 so as to adhesively secure the flaps 9-9 to the inside face of the adjacent center partition panels 1-1 as shown in Fig. 3, thereby completing the collapsed assembly of one pair of end cells. In substantially the same folding operation, the cross partition sections 6-6 associated with the right hand wings w2 and w-4 are folded along aligned scores 16-16 so as to place the cross partition sections 6-6 in overlying relation to the adjacent side wall liner sections 4-4. Adhesive strips c-c are then applied to the overfolded pair of center partition securing flaps 8-8 as shown in Fig. 3, and the right hand wings w-2 and w-4 then folded along aligned scores 12-12 so as to adhesively secure the glued flaps 8-8 to the adjacent center partition panels 1-1 as shown in Fig. 4, thereby completing the collapsed assembly of the other pair of end cells for this carrier.

The folding assembly of the top and bottom wings 111-5 and w6 is then ready to proceed to provide the intermediate cells for the carrier. In this operation, adhesive areas d-d are first applied to those portions of the center partition panels 1-1 to be covered by the adjacent center partition liner sections 51-51, and the top and bottom wings w-5 and w-6 are then folded along the longitudinal extending scores -50 to adhesively secure the center partition liner sections 51-51 to the adjacent center partition panels 1-1 as shown in Fig. 5.

In the next operation, adhesive strips e-e are applied to the center partition liner flaps 59-59 and the left hand portion of the wings w5 and W6 then folded along the aligned scores 65-65 to thereby adhesively secure the glue flaps 59-59 to the adjacent center partition liner sections 51-51 as shown in Fig. 6. In substantially the same operation, strips of adhesive f-f are applied to the end edge portions of the relatively wide side wall liner sections 54-54 as shown in Fig. 6, and the right hand portions of the intermediate cell forming wings w-5 and w6 are then folded along the aligned scores 62-62 to thereby adhesively secure the glued edge portions of the side wall liner sections 54-54 to the adjacent previously folded side wall liner sections -55 as shown in Fig. 7. As thus glued and folded the intermediate cells will be fully assembled in collapsed form and will lie between the collapsed end cells of the blank as shown in Fig. 7.

When the blank has been assembled into the form shown in Fig. 7, it is ready to receive the bottom and side panel forming blank B as shown in Fig. 2. In applying the blank B to the blank A assembled in the form shown in Fig. 7, adhesive areas g are first applied to the side wall liner sections 4 and 5 and to the partially overlapped side wall liner sections 54 and 55 as shown in Fig. 7, care being taken to apply no adhesive to the end panel section 2 or to the cross partition sections 7 and 52. One of the side wall panels 101 of the blank B is then applied in superimposed registry to the glued surfaces of the side wall liner sections 4, 5, 54 and 55 in the manner shown in Fig. 8. A coating 11 of adhesive is then applied to the entire face of the center partition panel 1, which can be done while the connected blanks are in the position shown in Fig. 8 or in the inverted position shown in Fig. 9. In the next folding operation blank A as shown in Fig. 9 is folded along the top edge defining score 11 to thereby adhesively secure the center partition panels 1 and 1 in back to back relationship as shown in Fig. 10.

In the next gluing operation, adhesive areas g are applied to the other set of side wall liner sections 4, 5,54 and 55 as shown in Fig. 10, care being taken to apply no adhesive to the intervening cross partition sections 7 and 52 or the end panel section 2. When thus glued, the blank B is folded along its bottom collapsing score 102 so as to place its side panel 101 into adhesive secured registry with the glued surfaces of the side wall liner sections 4, 5, 54 and 55, thereby completing the assembly of this twelve cell carrier in collapsed form as shown in Fig. 11.

The assembled blank part A of this carrier as shown in Figs. 12 and 13 provides a center partition structure which is formed by the center partition panels 1 and 1 as overlapped by the center partition liner sections 51- 51 and the paired center partition liner flaps 9-9 and 8-8. The handle part is of four ply construction at the ends thereof and of six ply construction at the hand grip area thereof. Two pairs of end cells are completely formed by the left hand wings w1 and w-3 and the right hand wings w-Z and w-4, while two pairs of intermediate cells are formed by the top and bottom wings w-5 and w6 of blank A as shown in Fig. 13. The other two pairs of intermediate cells are completed when the side panels 101 and 101 of the blank B have been secured to the side wall liner sections of the assembled blank part A. A collapsible twelve cell carrier which is sturdy and strong in construction is thus provided.

This twelve cell carrier may be erected by pressing its bottom collapsing score 11 against a fiat surface and thereupon retained in erected form by interlocking one pair of hook portions 22-22 formed in the bottom ends of the center partition panels 1-1 into engagement with the adjacent notched cutout 102 formed in the adjacent end of the bottom panel. To provide further support for the bottom panel, another pair of hook portions 22-22 may be formed in the bottom edge of the center partition panels 1-1 to interlock with the corresponding notch 102 formed in the opposite end edge of the bottom panel.

Multi-celled twin compartmented carriers constructed according to this invention are particularly adapted to receive bottles in the cells thereof, although these carriers can be designed for the transportation of various other solid articles as desired. The carrier shown in Figs. 12 and 13 is equipped with twelve cells designed to receive twelve bottles. However, these carriers can also be made to provide eight or ten cells if desired.

In making a ten cell carrier, the center partition panels 1-1 of the blank A shown in Fig. 1 would beappropriately reduced in length and the bottom and side panel forming blank B shown in Fig. 2 would also be appropriately reduced in length. To make the ten cell carrier by the use of the blank A shown in Fig. 1 for example, it is only necessary to reduce the width of the center partition liner sections 51-51, and remove the third pair of cross partition sections 57-57 and their associated securing flaps 59-59 so that the top and bottom wings w-5 and w-6 provide only two pairs of intermediate cross partition sections 52-52 and 53-53 and two pairs of side wall liner sections 54-54 and 55-55.

To provide an eight cell carrier, the center partition 1 panels 1-1 of blank A shown in Fig. 1 and the bottom panel sections -100 and the side panels 101-101 of blank B shown in Fig. 2 would be appropriately reduced in length. The paired center partition liner sections 51-51 would also be reduced in length and the I paired sections 53-53, 55-55 and 57-57 and the flaps 59-59 would be removed, thereby leaving only one pair of intermediate cross partition sections 52-52 and the associated side wall liner sections 54-54.

The mult-i-celledtwin conrpartmcnted article carriers made in accordance with this invention and equipped with any desired even number of cells are strong; and sturdy in construction and readily collapsible into flat form, and can easily be erected and maintained in erected position. The handle part for these carriers may be made of not less than four plys of sheet material with the: center partition structure extending down to the erected bottom panel and the full length of the carrier. The center partition: structure has a thickness of not less than two plys of sheet material throughout its length and height. The end panel sections extend down to the erected bottom panel and are integrally but foldably connected to the ends of the center partition panels to provide a carrier of great strength. All of the cross partition sections also extend down to the erected bottom panel and can be made of any desired height. The side panels: are also reinforced and strengthened by the side wall liner sections associated with the cell forming structures of the carrier.

Where the carrier is to be used in the transportation of heavy bottles or another heavy article loads, the bot torna nd side panel forming blank B" may be made from a stronger, tougher or heavier sheet material than that used to form the companion blank A. Carriers can thus be made in accordance with this invention to satisfy almost any use condition, and with a variegated number of even cells which are generally similar in design and appearance. eralliy similar in. structure irrespective of the number of cells with which they are equipped, the blanks therefor can: be assembled on substantially the same gluing and folding machines by making only selected adjustments of the gluing and folding devices thereof. As a result, substantial savings in production costs can be elfectcd where carriers having a variegated number of article receiving cells are to be produced.
